Android Google Maps resize marker on Zoom

Question

I need to display around 30 markers in a somewhat small area.

Is there a way to resize Google Maps API V2 markers when the user changes the zoom?

Or should I jus

If you want to do something when zooming, you can create a custom Mapview which extends the original MapView, and just override dispatchDraw(Canvas canvas).

With adding a little listener, you can do whatever you want in the callback. Something like this;

    @Override
protected void dispatchDraw(final Canvas canvas) {
    super.dispatchDraw(canvas);
    if (getZoomLevel() != lastZoomLevel) {
        if (listener != null) {
            listener.onZoom(lastZoomLevel, getZoomLevel());
        }
        lastZoomLevel = getZoomLevel();
    }         
}
